pySSHA 1.0.0

Description:

pySSHA 1.0.0

pySSHA-slapd
Python hashlib generator born as a script to test OpenLDAP user passwords.
It supports salted:

md5
sha1
sha224
sha256
sha384
sha512

Introduction
pySSHA-slapd is a simple SSHA string encoder e checker that's quite easy to use:
python3 ssha.py -p slapdsecret
{SSHA}omu7YHgg6_uqOIN_epZtfJtGo0ruwdSr

Usage
usage: ssha.py [-h] -p P [-s S] [-salt_size SALT_SIZE] [-c C] [-enc ENC] [-b]
[-prefixed] [-d D]

Usage: python ssha.py -p Password[-c SSHA hash to check]

optional arguments:
-h, --help show this help message and exit
-p P Password to encode
-s S Salt, 4 bytes in hex format, example "fooo": -s
666f6f6f
-salt_size SALT_SIZE salt lenght
-c C {SSHA} hash to check
-enc ENC Encoder to use, example: sha1 sha224 sha256 sha384
sha512
-b if {SSHA} hash is in base64 format
-prefixed if suffixed or prefixed salt
-d D Debug level from 1 to 5


Dependencies
Python3 and hashlib
Usage examples
You can adopt a specified salt for hashing, in hex format:
python3 ssha.py -p slapdsecret -s 74be2629
{SSHA}w5CJCwNQk44NjTYzcMZNKbE6Bu90viYp

Verify if a password is valid comparing it with a SSHA hash:
python3 ssha.py -c {SHA1}pPUGnEBCmIa+fJy6ZTS87eEg+ylVYDqcrs6oHA== -p slapdsecret

Same as previous but ssha hash is in base64 format (like ldapsearch output):
python3 ssha.py -c e1NIQTF9dzVDSkN3TlFrNDROalRZemNNWk5LYkU2QnU5MHZpWXA= -b -p slapdsecret -salt_size 4

Same as the previous but with maximum debug level
python3 ssha.py -c e1NIQTF9dzVDSkN3TlFrNDROalRZemNNWk5LYkU2QnU5MHZpWXA= -b -p slapdsecret -d 3 -salt_size 4

[sshaSplit debug]

salt: 74be2629
password: slapdsecret

{SSHA} Check is valid: True

select your preferred encoder
python3 ssha.py -p slapdsecret -s 74be2629 -enc sha512
{SHA512}4gm2Ep0Nklb8pkss9zIs+t6/BGaGn2QYphl3UeAYuBBNW/hj8glu4jUb7JPb4LVWdCv+g0WoyYUB9VWVajQpjHS+Jik=

without salt
python3 ssha.py -p ciao -d 3 -salt_size 0 -enc sha512

OpenLDAP use a 8byte lenght salt, you can also change this value with -salt_size option.
